Pondering sperm and semen and wondering how they differ? Semen and sperm are kinda like squares and rectangles. Semen, also called ejaculate or cum, is the whitish fluid that comes out of the penis when a person comes — well, usually, but not always. I mean, both come out the same place, after all.
